Be it known that l, ANTHo-NY Fnicnnn, ajcitizen of the United States, andresident s of Cleveland, in the county @of vCuyahoga.

and State of Ohio, have invented new and l ,useful Improvements Ain Sand and Gravel Spreaders, of which the'following isla description, reference being had to the accompanying drawings, `which are a part ofthls specification.l f i i, c f i L The invention relates to a device for spreading' sand or similar material `upon the surfaceof aroad during paving operations.

One ofthe objects of the invention is to provide a spreader which maybe operated by beingpushed ahead of a motor truck so that the sand orfotherv material willbe deposited `over the freshly prepared road ahead of the truck, a feature which is'especially advantageous in the `making of roads `in which a. coating of bituminous `material is spread upon a layer of; rock and is then' covered over with sand, gravel or linelycrushed stone; j 1

A further object ofthe invention is to provide means for lspreadiing' material overy different widths of roadway. i f fr l. t*

f A still further object of this invention is `to provide a device of the `class described having .means for readily adjusting the depth and ywidth lof the materials discharged therefrom. i i

, With the above and otherobjects in view which will appear as the `description proceeds, my invention resides in the novelcon- Y 4struction, combination and arrangement of lparts'substantially as hereinafter described ,and more particularly Adeined by the appended claims, it being understood that such changes in the 1 precise embodiment-of the tion taken lon the line 3 3' of Fig 1` and looking inthe direction of the` arrows; Fig.

`the members 15.

to different depths upon sa id rods `27" '1- isa detail view of side of the conveyor; Fig..5 is a `detail sectional view through one `of the wheelsv and *the Conveyor.` ,i y. i

In the drawings, then'umeral 6 designates i This conthe spreadergc'onveyor `as a whole;

plurality of transversely plateseach of which is pivotsecured adjacent its ends to chains S- by extending 10 which pass through the links of the chain, adjoining plates' being secured to adjoining so that'the front edges 11 of the plates slightly overlap the rear edges of the The conveyor `runs over two sets of rollers or wheels 13vwhich are mounted on shafts let secured to side frame members 15.' Each roller 13 is provided with a centrally dis- Dosed 'annular groove 16 in which the chain 8 runs and witha plurality offradially disposed recessesl for receiving' the projected ends Vof the pins 10 whereby a driving con jnection isformed between each set of roll- `'ers and the conveyor.

The lower run of the conveyor"formsav track upon which the device moves and is held flat between the rollers 13 by means of rollers 18 running on the ehainlinks and carried by shafts 19 journalled in `brackets 2O secured to the memsupported and braced 21 and side plates`22 brace members 22- by 5a; central plate shoe secured to transverse which yare connected to A top frame, consisting brace members 27, is secured to the frame members 15 by connections between the ,members23 and 24 and said members 15.

' lnorder thatthe material may be spread the road and varying widths of road' covered, l provide a gate which, is adjustable vertically' with yrespect to the conveyor' to vary the thickness Aof the -a portion of the undern of uprights 23 N24, side members I25, end members l26 `and bers15. The upper `run `of the conveyor is layer of the material. spreadl by the conveyor,

and `which is adjustable laterally so as to vary the eiiective delivery width 'ofthe conveyor. j f

The said gate comprises two plates 25',

pivotally connected together at Jtheir i inner ends 26 and provided at their outer ends with thebored and threaded bosses^28 which engage the threaded rods 27', whereby the said :plates may be verticallyv adjusted. The

are `rotatably mounted in bosses `channel guideways 30 in which 28 carried by one end of the side-plates 29, which plates are pivotally mounted at their other ends 29 between the bearings 30rigid with the side frame member 25. vThe inner ends of said plates 29 are provided with 3l of the plates 25 loosely fit. The plates 25 at their hinged connection have upturned lower edges to form a shoe 32 which will press the advancing edges of the plates 1l of the conveyor downwardly in case said edges should project upwardly to suchan extent as to engage the lower side edges of said plates 25. The plates 25 carry a hinge Pivot 33 which is provided With @guide P111' y ley 34 and a chain 35 passes over thispulley and around sprockets 36 .carried by the rods 27 so that by turning either of these rods the plates 25 may besimultaneously adjusted vertically above the conveyor for the purpose previously described. The plates 25 are pivotally connected vat their outer ends to collars 27 pivotally secured to the bosses 28 and having threaded bores and a shaft 38'having oppositely threaded ends seated in said bores provides means for moving the outer ends of said plates toward or away from eachother to vary `the' edective delivery width of the conveyor, the side plates 29 swinging inwardly when theplates move inwardly on the turning of a hand wheel 39 on the shaft 38. l

` :For the purpose of feeding the material to be spread by the conveyor onto the same Iprovide a hopper or bucket 40 pivotally secured at its dumpingend to shaft 41 carried by the top frame and adapted to be raised. and'lowered by means of cables 42 running over drums 48 on ashaft 44, pulleys 45 on the top frame and pulleys 46 on the bucket as shown in Fig. l with "a pawl 47 and ratchet 48 for securing the cable against backward movement, the shaft 4l. being turned by a crank 49 or other suitable'means. To enable the device to be pushed ahead of the propellingI vehicle-I provide bumpers 50 l secured to or integral with the frame members l5. j

With the construction above described the plates 25 are. :set the desired vertical distance above the conveyor 6 and their outer ends are set to the width desired and the material fed to the conveyor from the elevated hopper 40. From the foregoing description, it will be readily apparent that the control gate is yin two partsr or sections, the plates 29fforming one' partv and the plates 25 the other, and the section formed byV plates 29, the lower edges of which are atall times inclose proximity to the bottom of the hopper which is formed by the vupper run of the endless conveyor, controls the width at which the material isv discharged from the device. The adjustment of the plates 29 to varythe t widthl at which the materials are discharged extensions f isengageable with either of the rods 27 as will be readily obvious.

The propelling vehicle -pushingthe 'spreaderahead of it causes the conveyor to move overr the rollers 13 and carrythematerial forwardly and deposit it in frontlof the advancing conveyor and propelling ve"` hicle.` Thus the sand or gravel may be laid upon the freshly prepared road and much llabor saved as it hasheretofore been the vpractice to spread the'sand or gravel upon the road by hand shovelling.
